Bounce Flash

Bounce flash is a flash technique where the head points at a ceiling, wall, or reflector instead of straight at the subject. The surface reflects the burst back as a broad, soft spread of light. Shadows fall gently, skin keeps texture, and the result looks closer to natural room light than to a direct camera flash. Most speedlights support it with a tilting and swiveling head, on the camera or off it.

Softness depends on the size of the light source relative to the subject. A bare flash tube is a few centimeters wide, so it casts hard shadows with sharp edges. Bouncing the burst off a ceiling turns a patch of the ceiling into the light source, often a meter or more across. The larger the source, the more the light wraps around the subject and the softer the shadow edges become.

A tilt between 45 and 90 degrees covers most rooms. For a subject a few meters away under a standard ceiling, 45 to 60 degrees places the reflected light in front of the subject rather than on top of the head. Straight up suits close subjects. Swiveling the head toward a wall behind or beside the camera adds direction and works when the ceiling is too high or too dark.

White and pale neutral surfaces work best because they return most of the burst without changing its color. Standard white ceilings, light gray walls, and white reflector cards are all common choices. Dark surfaces absorb the light and colored surfaces tint it. Glossy surfaces can throw a visible hotspot back into the frame, so matte surfaces give more even results.

Yes, when the surface has a color of its own. The reflected light picks up the surface color and carries it onto the subject, so a wooden ceiling adds an orange cast and a green wall adds green. Mild casts can be corrected with white balance in editing, especially in raw files. Strong casts on skin are hard to remove, so a neutral surface is the safer choice.

More than direct flash. The light travels from the flash to the surface and then to the subject, and the surface absorbs part of the burst. Two to three extra stops is a common starting point, through higher flash power, a wider aperture, or a higher ISO. TTL metering handles much of this automatically because it reads the light after the bounce.

A bounce card is a small white card built into many speedlight heads or attached to them. With the head tilted up, the card pushes a small part of the burst straight forward. That forward sliver fills shadows under the brows and chin and adds catchlights to the eyes while the ceiling bounce does the main work. Many photographers pull the card out for indoor portraits by default.

Rarely. Bounce flash needs a surface to reflect off, and open sky returns nothing. Outdoors, a nearby pale wall, a reflector held by an assistant, or the inside of a doorway can stand in for a ceiling. Without a surface, direct flash with a diffuser or an off-camera flash in a modifier is the better tool.

Yes. Through-the-lens metering reads the light coming back through the lens during a pre-flash, so it measures the bounced light rather than guessing at the geometry. That makes TTL a good match for bounce flash, since the path length and surface loss change from room to room. Photographers often add positive flash exposure compensation when results come back dark.

Bounce flash fails when nothing useful surrounds the subject. High ceilings in churches and concert halls return too little light. Black ceilings in clubs absorb the burst. Colored surfaces tint skin. In those rooms, photographers switch to direct flash softened with a diffuser, or bring the light off camera with a modifier. Battery drain also rises because each bounced burst uses more power.
